Totally just got my copy of Guitar Hero Van Halen in the mail today. 
 
   
 
 
Yeah, came in a little cardboard sleeve like Wii Sports and stuff like that. Gives you a website for the game manual and such like that. 
 
Now, my true question as to if it has the neat features of GH5 is about to be answered. *pops it in* 
 
It doesn't have the Party Play option that GH5 has, but it has a neat little intro like Guitar Hero Metallica does. Eddie playing Eruption and stuff. No, I don't know why I am not playing it though...  
 
Ok, I just played a song and then immediately played an encore... Yes, this seems to be exactly what Guitar Hero Metallica did a few months ago. This game seems like it should have come out before GH5, simply because Guitar Hero made a lot of great innovations in 5 and now this one is going back on that.  
 
On a note of Achievements, this game is the most relentless GH game since GH3. There are separate achievements for 5 starring every song in career on expert, for each instrument... You can see them for yourself here of course.  http://www.giantbomb.com/guitar-hero-van-halen/61-25536/achievements/ 
 
Lastly, the setlist in this game is at least looking to be awesome, like Guitar Hero Metallica. If you like Van Halen, I think you will like the stuff on here. Some notable side act songs are as follows: Semi-Charmed Life by Third Eye Blind, Double Vision by Foreigner, and... Stacy's Mom by Fountains of Wayne... Yeah, that is on here... 
 
Initially quite sad that GH5's innovations are absent from this game, but I guess that is just because Guitar Hero doesn't like me enough to have a good interface / career AND a good setlist at the same time... I guess I'll have to make due.
